Abstract

In a process of producing composite materials consisting of sheet metal plates, metal strips and foils and provided with a skeleton surface structure, a layer of a metal powder which is difficultly flowable and consists of irregularly shaped particles is applied to a continuously moved metallic carrier layer and is bonded to said carrier layer by cold roll cladding and is sintered in a reducing atmosphere at temperatures of 600.degree. to 1000.degree. C. In order to produce composite materials in which the skeleton structure constitutes a layer that is of uniform thickness throughout the surface and is firmly bonded to the carrier layer, the metal powder is uniformly distributed and applied as regards its bulk volume using a distributing roller, which rotates opposite to the main direction of movement of the carrier layer, whereby a uniform thickness is obtained.
